vendor immediately.
Controller and Interface
Each controller comes with pre-installed DIMM module(s).
The traditional battery backup is replaced by an innovative Cache Backup Module
methodology (CBM) which consists of a super capacitor and a flash backup module (FBM).
Cached data is quickly distributed to a flash backup module for permanent storage with the
support of the super capacitor in the event of a power outage. The advantage of a super
capacitor is its very fast charging time. The super capacitor is charged within a few minutes
and available to distribute power to the controller. Cached data can be saved immediately
and permanently in flash backup module (FBM).
The embedded firmware features intelligent algorithms, such as power-saving modes,
variable fan speeds, and exiled drive handling, making this model a greener choice.
Expansion Enclosure Controller and Interface
The enclosure is managed by expander controllers that distribute data flow to individual disk
drives and report operating status through a proprietary enclosure service via in-band
protocols. The enclosure, along with other expansion enclosures, connects to a Unified
Storage System and serves as a building block of a scalable configuration.
In terms of supported protocols, the firmware supports communications with enclosure
devices, SAS/SATA disk drives and as Unified Storage System featuring SAS expansion
ports.
In terms of physical connection, the SAS interface provides ease of cabling through Mini-
SAS connectors. With a backplane adapting SAS or SATA drives, the system supports
enterprise-class SAS, Near-line SAS, cost-effective SATA-II or SATA-III hard drives or
SSDs, and is ideal for adding large capacity to a storage pool.
